SPECIFICATION forming part of Letters Patent No. 787,306, dated April11, 1905. Application filed February 10, 1904:. Serial No. 192.980-

T!) lllllilH it Ill/M l] WWI/Peru.-

Be it known that l. FRANK B. Moss, a citizen of the l nitcd States, anda resident of Denver. in the county of Denver and State of oloiadohaveinvented a new and useful lnii provement in Detachable lleels, of whichthe i following is a specification.

My invention relates to an improvement in detachable andintei'chaiigcable heels.

The object of this invention is to provide a device which will act as asupport for bracing and strengthening shoes and at the same time providesimple means for conveniently replacing worn heels at small expensewithout the necessity of going to a shop to have it done. ln otherwords, the invention has in view the provision ofheels as independentarticles of manufacture, such heels having means connected therewith forquickly, easily, and accurately fastening them to a shoe and fordetaching them when occasion for removing a worn heel arises.

My invention consists in certain novel features of construction andcombinations of parts, which will be hereinafter described, and pointedout in the claims.

in the accompanying drawings, Figure 1 a bottom view of the heel-plate.Fig. 2 is a section of the same. Fig. 3 is a view of the interior of myimproved form of locking-plate in its prcfcrred construction. Fig. 4 isa section through the heel and locking plates.

Figs. o, 7. s, E). 10, and ll are views of i slightly-modilied forms oflocking plate, and locking mechanism more particularly; and Fig. 12 is adetail view of the screw 26.

A represents a heel-plate made in the form r of the usual heel of a bootor shoe and adapted to be secured to the heel portion of the solo in anyapproved manner. This plate is preferably provided at or near its centerwith a loop. or it might be a hook l,preferably diagonallv placed, asshown in Figs. 1 and 3.

.llikewise the heel-plate is preferably furnished with several holes 2 2-say threearranged triangularly. The purpose of the loop orhook and theholes will presently be explained.

B indicates the locking-plate, which in the various forms is the same inoutline, it being made to conform in shape to plate A, which it fits.The heel forms a part of or is secured to this locking-plate B in anyapproved manner. The locking-plate has a chambered-out interior 3, or itmay be made of two outer plates spaced apart by suitable filling-blocksat the edges and riveted or otherwise secured together.

A locking-lever ii is pivoted at one end in the chamber 3, and thislever is provided with I a tongue -t, preferably curved in the arc of acircle from the pivot of the lever as a center. This tongue mayhave acam or tapering outer surface, if desired. and is adapted to enter theloop or hook l and draw the locking-plate sei curely against theheelplate, whereby to attach the heel rigidly to the boot or shoe. Athuiiibpiece 5, connected with the free end i of the lever L, is adaptedto be manipulated to force the tongue 4 in or out of the loop or i hook.The outward movement of the lever is limited by the wall 6 of thechamber and the inner movement by the thumb-piece 5, i which when forcedinward onlyprotrudes sufficiently to afford a means of operating theleyver and hardly enough to be visible, it being on the inside or iorwardedge of the heel. Dowelpins '7 7 project upwardly from the llockingplatc at positions apart correspondi ing to the holes 2 2 in theheel-plate A, they 1 being adapted to enter said holes and insure theright position of the heel when attached. These dowel-pins hold thedetachable heel against lateral movement or any tendency to twist, andthe locking-lever secures the heel to the heel-plate. Obviously theholes 2 2 and pins 7 7 might be transposed. This is likewise true, ofcourse, of the other parts of the lock.

Various modiiications might be made, some of which I have illustrated.For iiistance, in Fig. the loop 1 instead of eX tending diagonally isdisposed transversely and slide-plate ll), provided with an elony gatedslot 1 1, held by a pin 12, is arranged to slide LlKlWlSC or lengthwiseof the heel into the loop, the outer end 13 of the plate being in theform of a thumb-piece, by which i the plate is manipulated.

Fig. 6 illustrates a form very similar to that shown in Fig. 3. In Fig.7 this idea is slightly modified, the plate 14 being confined within thechamber of the locking-plate B, and a lever 15, pivoted at 16, has athumb-piece 17 pivoted to its free end and extended out through theforward edge of the heel in position to be pushed in or out to force thetongue 14 in or out of the loop 1.

In Fig. 8 an open hook 1 is provided in lieu of the loop, and ahand-lever 18 is pivoted at 19 and carries a segment 20 at the innerend, adapted to be turned beneath the hlook, whereby to lock the heel tothe heelp ate.

In the modified construction shown in Fig. 9 a crank-shaft 21 is pivotedin bearings 22 22 and provided with an angular outer end 23, adapted toreceive a key, whereby the crank portion 24 is turned or rocked beneaththe hook 25.

In the construction illustrated in Fig. 10 a screw 26 is provided with apinion 27, which is turned by a gear-wheel 28, a portion of the teeth ofwhich are accessible from the forward edge of the heel where it isturned, the screw taking into screw-thread formed in the heel-platesecured to the heel portion of the sole.

In Fi 11 the screw is provided with a worm-w1eel 29, operated by a worm30 on shaft 31, the outer end 32 of which is constructed to receive akey. A heel provided with any one of these attachments may be quicklyapplied or removed when occasion 3 may require it, either to attach anew heel or remove a heel already applied.

In addition to the forms described various other slight changes might beresorted to in the form and arrangement of the several 4 parts describedwithout departing from the spirit and scope ofmy invention, and hence Ido not wish to limit myself to the precise constructions herein setforth; but,

Having fully described my invention, what 4 I claim as new, and desireto secure by Letters Patent, is-

1. The combination with a heel-plate, of a chambered-outfastening-plate, one having pins and the other holes to receive saidpins, 5 and locking means, a part of which is connected with each plate,said locking means independent of the pins.

2. The combination with a heel-plate having a centrally-locatedfastening means, of a 5 chambered-out fastening-plate, having lookingmechanism thereon, one of the plates being provided with pins and theother with holes for the reception of the pins, said locking mechanismengaging and fastening the heel 6 to the said centrally located lockingmeans.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
